EDGAR Form 144
Form 144 notices, filed when an insider intends to sell restricted stock. Usually precedes the completed sale on Form 4.
edgar_form144 — the dataset name to pass to the Obscura API.
What one row means
One proposed-sale line (a single securitiesInformation entry) from an SEC Form 144 "Notice of Proposed Sale of Securities" filing — the leading indicator that an affiliate intends to sell restricted/control stock, pairing with the lagging Form 4 confirmation. Legacy pre-2022 plain-text 144s produce a single stub row (seq 0) carrying only issuer identity from the SEC-HEADER.
One row per (filename, seq) — one EDGAR submission filename plus the zero-based index of the securitiesInformation block within that filing's XML..
Point-in-time availability
Every Obscura dataset carries available_date: the calendar day the publisher made the row
available, day-of, with no session rounding. It is the one column a backtest filters on, and it means the
same thing on every dataset in the catalog.
For edgar_form144: filing_join: available_date = the filing's EDGAR dissemination date, recovered from edgar_filings via filename — the point-in-time anchor (occurred_on is the affiliate's approximate PLANNED sale date, a separate future-facing field, not the availability basis).
Refresh cadence
Obscura refreshes edgar_form144 every weekday — the most frequent scheduled job that re-collects or re-exports it. This is Obscura's own pipeline cadence, not the upstream publisher's release schedule; when a row became public is recorded per row in available_date.

Frequently asked questions
What is in the edgar_form144 dataset?
Form 144 notices, filed when an insider intends to sell restricted stock. Usually precedes the completed sale on Form 4. One proposed-sale line (a single securitiesInformation entry) from an SEC Form 144 "Notice of Proposed Sale of Securities" filing — the leading indicator that an affiliate intends to sell restricted/control stock, pairing with the lagging Form 4 confirmation. Legacy pre-2022 plain-text 144s produce a single stub row (seq 0) carrying only issuer identity from the SEC-HEADER.
How do I avoid look-ahead bias with edgar_form144?
Filter on edgar_form144.available_date, the day the publisher made the row public. For this dataset that date is derived as follows — filing_join: available_date = the filing's EDGAR dissemination date, recovered from edgar_filings via filename — the point-in-time anchor (occurred_on is the affiliate's approximate PLANNED sale date, a separate future-facing field, not the availability basis). A query of the form WHERE available_date <= '<as-of date>' never sees a row before it existed.
In what formats can I get edgar_form144?
As a Parquet bulk export (POST https://api.obscura.trade/v1/download) or as JSON from the typed query API (POST https://api.obscura.trade/v1/query), both with dataset="edgar_form144". The column schema is public at https://api.obscura.trade/v1/catalog/edgar_form144.
Can I filter edgar_form144 by company or symbol?
Yes. edgar_form144 carries cik, the column the API's symbols filter resolves against.
How often is edgar_form144 updated?
Obscura refreshes edgar_form144 on a every weekday schedule — that is the most frequent scheduled job that re-collects or re-exports the table. It is Obscura's own pipeline cadence, not the upstream publisher's release schedule; when the publisher makes a row available is described by the availability rule above, and is recorded per row in available_date.
